Attaching the Telescope to the Mount (For G-8N)

NOTE:

Before you attach the optical tube, fully tighten the right ascension and declination clamps. This will prevent the telescope from moving suddenly once attached to the mount.

1Locate the mounting bracket from the box containing the equatorial mount head.

2Attach the mounting bracket to the tube rings so that the tappered (narrow) end is against the bottom of the tube rings.

3Loosen the hand knob on the side of the CG-5 mount.

4Slide the mounting bracket that is attached to the bottom of the tube rings into the reccess on the top of the mounting platform (see figure 2-8).

5Tighten the telescope mounting screw on the CG-5 mount to hold the telescope in place.

6Hand tighten the mounting platform safety screw until the tip touches the side of the mounting bracket (see figure 2-5).

Never loosen any of the knobs on the telescope tube or mount. Also, be sure that the open end of the telescope is pointing away from the ground at all times.
